B. Proton Events
The S1 (Minor) solar radiation storm which began at 18/1525 UTC ended at 20/1155 UTC and reached a maximum value of 58 pfu at 19/0105 UTC.
C. Geomagnetic Activity Summary
The geomagnetic field reached G1 (Minor) geomagnetic storm levels at 20/1200-1500 UTC followed by active conditons for the remainder of the period due to coronal mass ejection (CME) effects.
